So the priest Zadok, the prophet Nathan, Benaiah son of Jehoiada, and the Cherethites and the Pelethites went down and had Solomon ride on King David’s mule and led him to Gihon.
the priest Zadok and the prophet Nathan have anointed him king at Gihon, and they have gone up from there rejoicing, so that the city is in an uproar. This is the noise that you heard.
